ABSTRACT
Objective@#This study aimed to investigate whether cytokine profiles and virological markers might add value in monitoring the effects of peginterferon (PEG-IFN) therapy for hepatitis B e-antigen (HBeAg) positive chronic hepatitis B (CHB).@*Methods@#HBeAg positive patients with CHB were treated with PEG-IFN for 48 weeks. Clinical biochemical, and HBV serological indexes, as well as cytokines, were detected at baseline and every 12 weeks.@*Results@#A total of 116 patients with CHB were enrolled in this study; 100 patients completed the 48-week treatment and follow-up, of whom 38 achieved serum HBeAg disappearance, 25 achieved HBeAg seroconversion, 37 showed HBsAg decreases ≥ 1 log 10 IU/mL, 9 showed HBsAg disappearance, and 8 became HBsAb positive. The cytokine levels at baseline and during treatment were similar between the HBeAg disappearance group and non-disappearance group. The disappearance of HBeAg was independently associated with HBeAg levels at weeks 12 and 24, and with the HBeAg decline at week 24 ( P < 0.05). The HBsAg response was independently associated with HBsAg, the HBsAg decline, HBeAg, the HBeAg decline at week 12, and HBsAg at week 24 ( P< 0.05).@*Conclusion@#There was no significant correlation between the response to interferon (IFN) and cytokines during PEG-IFN treatment. The changes in virological markers predicted the response to IFN after 48 weeks.
